摘要
对玉米黄色素的相关提取因素进行了系统的研究,试验结果表明:玉米黄色素的最大吸收波长为446 nm,95%的乙醇对玉米黄色素的提取效果最佳;采用正交试验确定浸提法的最佳工艺条件为:提取液的pH值为6.00时,提取料液比为1∶8,提取温度为65℃,浸提时间为2.5 h。
The extraction condition of the yellow pigment from the maize powder are studied. Results show that the maximum absorbance wavelengh of the maize yellow pigment is 446 nm, and the 95% alcohol solvent is optimal for the extraction. The optimal extraction conditions obtained from the orthogonal experiment are as following： the pH value of the extraction reagent equals 6. 00, the weight ratio of the extraction reagent to the maize powder equals eight, the temperature is 65℃ and the extraction time is 2. 5 hours.
